Description

Technical Field

[0001] This invention relates to the field of dental implant technology, specifically to a segmented dental implant connection structure that enables adaptive stress adjustment. Background Technology

[0002] Dental implants, also known as dental implants or artificial tooth roots, are devices surgically inserted into the jawbone at the site of edentulism to support the prosthetic tooth. The implantation process begins with a comprehensive preoperative evaluation of the patient, including oral examinations and imaging studies, to determine if the alveolar bone condition and overall health are suitable for the surgery. Then, under local anesthesia, the gingiva is incised, the implant socket is prepared, the implant is inserted, and the gingiva is sutured. After implantation, a healing period of 3-6 months is generally required for the implant to integrate with the bone tissue. Finally, the abutment and artificial crown are installed to complete the tooth restoration. A dental implant typically consists of an implant body, an abutment, and a crown. The implant body is the part inserted into the human tissue; the abutment is the part exposed outside the mucosa, providing support, retention, and stability for the artificial prosthesis above it. Current dental implants are generally made of metal, connected by threads between the metal parts, relying on rigid osseointegration as their core. This lacks the physiological buffering function of the natural periodontal ligament and is considered a "hard connection" design, which has the following drawbacks: Occlusal overload can easily lead to stress concentration, increasing the risk of bone resorption, screw loosening, or implant fracture. It lacks fine tactile feedback, resulting in a noticeable "dull" feeling during chewing. Unlike natural teeth, it cannot regulate occlusal force through nerves. Long-term rigid force transmission may have adverse effects on the implant-bone interface and opposing teeth. Therefore, to address the above problems, a segmented oral implant connection structure that can achieve stress adaptive adjustment is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a segmented dental implant connection structure that enables adaptive stress adjustment, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: including an implant, a repair abutment, a buffer, and a central screw; The implant has a prosthetic abutment installed inside, and a buffer is installed above the prosthetic abutment to provide cushioning. The buffer has a central screw inside, and the outside of the central screw is spirally connected to the prosthetic abutment. The buffer includes a disc-shaped limiting cover with a recessed groove at the bottom. Multiple evenly distributed buffer sleeves are arranged inside the groove, and the top of the buffer sleeves is fixedly connected to the limiting cover. The buffer sleeve is installed inside the repair base; A recessed groove is provided in the center of the limiting cover, and a limiting sleeve that is fixedly connected to the limiting cover is provided below the recessed groove.

[0005] As an optional solution of the segmented dental implant connection structure that enables stress adaptive adjustment as described in this invention, the buffer includes a hollow sleeve that is fixedly connected to the limiting cover. A movable column is provided on the inner side of the hollow sleeve. An upper unit buffer pad is fixedly connected above the movable column, and a lower unit buffer pad is fixedly connected to the bottom of the movable column.

[0006] As an alternative to the segmented dental implant connection structure that enables adaptive stress adjustment as described in this invention, both the upper unit buffer pad and the lower unit buffer pad are made of PEEK material.

[0007] An implant typically consists of a body, a neck, and an abutment or abutment. The body is the part implanted within the human tissue; the neck connects the body to the abutment or abutment; the abutment or abutment is the part exposed outside the mucosa, providing support, retention, and stability for the superimposed artificial prosthesis. Current dental implants are generally constructed of metal, connected by threads, relying on rigid osseointegration. This lack of natural periodontal ligament's physiological buffering function constitutes a "hard connection" design, which has the following drawbacks: overload during occlusion can easily lead to stress concentration, increasing the risk of bone resorption, screw loosening, or implant fracture; it lacks fine tactile feedback, resulting in a noticeable "dull" feeling during chewing; it cannot regulate occlusal force through nerves like natural teeth; and long-term rigid force transmission may adversely affect the implant-bone interface and opposing teeth. To address this, a limiting cover is placed above the abutment, with several buffer sleeves at the bottom. Movable posts are inserted inside the hollow sleeves of the buffer sleeves, with upper and lower unit buffer pads respectively positioned on the axial upper and lower sides of the moving posts. During the biting action, the limiting cover will drive the hollow sleeve below it to slide along the outside of the moving post. The upper unit buffer pad and the lower unit buffer pad can achieve a buffering effect through their own deformation, thereby completing the adaptive adjustment of the biting state. This can effectively avoid the stress concentration problem during biting, eliminate the discomfort caused by biting, and at the same time avoid adverse forces on the opposing teeth.

[0008] As an alternative solution to the segmented dental implant connection structure that enables stress adaptive adjustment as described in this invention, the implant includes a connector and a central post. The connector has external threads on its outer side, and a central post is located in the center of the inner side of the connector. The bottom of the central post is fixedly connected to the connector, and the outer side of the central post is spirally connected to the prosthetic abutment.

[0009] As an alternative solution to the segmented dental implant connection structure that enables stress adaptive adjustment as described in this invention, the restoration abutment includes a connecting post that is spirally connected to the inside of the connector. The bottom of the connecting post is fixedly connected to an internally threaded connecting sleeve, the inner side of which is spirally connected to the implant. An abutment is fixedly connected to the top of the connecting post, and a threaded hole that is spirally connected to a central screw is provided at the center of the top of the abutment.

[0010] As an alternative to the segmented dental implant connection structure that enables adaptive stress adjustment as described in this invention, the surface of the abutment is provided with uniformly distributed limiting holes.

[0011] The mating structure formed by the connecting post of the repair abutment and the internally threaded connecting sleeve can be assembled with the connector and central post of the implant. The connection structure adopts the form of internal and external threads, which can ensure the connection strength and tightness between the implant and the repair abutment, prevent the connection from loosening, and thus avoid negative impacts on the stability and effectiveness of the implant.

[0012] Compared with the prior art, the beneficial effects of the present invention are: By setting a limiting cover above the restorative abutment, and configuring several buffer sleeves at the bottom of the limiting cover, a movable post is installed inside the hollow sleeve of the buffer sleeve. On the upper and lower sides of the movable post along the axial direction, an upper unit buffer pad and a lower unit buffer pad are respectively set. During the occlusal action, the limiting cover will drive the hollow sleeve below it to slide along the outside of the movable post. The upper unit buffer pad and the lower unit buffer pad can achieve a buffering effect through their own deformation, thereby completing the adaptive adjustment of the occlusal state. This can effectively avoid the stress concentration problem during the occlusal process, eliminate the discomfort caused by occlusion, and at the same time avoid adverse forces on the opposing teeth.

[0013] The mating structure formed by the connecting post of the repair abutment and the internally threaded connecting sleeve can be assembled with the connector and central post of the implant. The connection structure adopts the form of internal and external threads, which can ensure the connection strength and tightness between the implant and the repair abutment, prevent the connection from loosening, and thus avoid negative impacts on the stability and effectiveness of the implant.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1 Please see Figure 1 , Figure 3 and Figure 4 The present invention provides a technical solution: A segmented dental implant connection structure that enables stress adaptive adjustment includes an implant 1, a prosthesis abutment 2, a buffer 3, and a central screw 4. The implant 1 has a repair base 2 installed inside, and a buffer 3 for cushioning is installed above the repair base 2. The buffer 3 has a central screw 4 inside, and the outside of the central screw 4 is spirally connected to the repair base 2. The buffer 3 includes a limiting cover 301 arranged in a disc shape. A recessed groove 302 is provided below the limiting cover 301. Multiple evenly distributed buffer sleeves 303 are provided inside the groove 302. The top of the buffer sleeves 303 is fixedly connected to the limiting cover 301. The buffer sleeve 303 is installed inside the repair base 2; The center of the limiting cover 301 is provided with a recessed groove 304, and a limiting sleeve 305 is provided below the recessed groove 304 and is fixedly connected to the limiting cover 301.

[0018] The buffer component 3 includes a hollow sleeve 3031 that is fixedly connected to the limiting cover 301. A movable column 3032 is provided on the inner side of the hollow sleeve 3031. An upper unit buffer pad 3033 is fixedly connected above the movable column 3032, and a lower unit buffer pad 3034 is fixedly connected to the bottom of the movable column 3032.

[0019] Both the upper unit cushioning pad 3033 and the lower unit cushioning pad 3034 are made of PEEK material.

[0020] Dental implants typically consist of a body, a neck, and an abutment or abutment. The body is the portion implanted within the human tissue; the neck connects the body to the abutment or abutment; and the abutment or abutment is the portion exposed outside the mucosa, providing support, retention, and stability for the superimposed artificial prosthesis. Current dental implants are generally constructed of metal, connected by threads between the metal components, relying on rigid osseointegration. This lack of natural periodontal ligament cushioning function constitutes a "hard connection" design, which has the following drawbacks: it easily leads to stress concentration under occlusal overload, increasing the risk of bone resorption, screw loosening, or implant fracture; and it lacks fine tactile feedback, resulting in a "dull" feeling during chewing. Obviously, unlike natural teeth, occlusal forces cannot be regulated by nerves. Long-term rigid force transmission may have adverse effects on the implant-bone interface and opposing teeth. By setting a limiting cover 301 above the restorative abutment 2, and configuring several buffer sleeves 303 at the bottom of the limiting cover 301, a movable post 3032 is inserted inside the hollow sleeve 3031 of the buffer sleeve 303. On the upper and lower sides of the axial direction of the movable post 3032, an upper unit buffer pad 3033 and a lower unit buffer pad 3034 are respectively set. During the occlusal action, the limiting cover 301 will drive the hollow sleeve 3031 below it to slide along the outside of the movable post 3032. The upper unit buffer pad 3033 and the lower unit buffer pad 3034 can achieve a buffering effect through their own deformation, thereby completing the adaptive adjustment of the occlusal state. This can effectively avoid the stress concentration problem during the occlusal process, eliminate the discomfort caused by occlusion, and at the same time avoid adverse forces on the opposing teeth. Also includes the following: The upper unit buffer pad 3033 and the lower unit buffer pad 3034 are made of rubber and have a certain buffering effect. When the patient bites, the limiting cover 301 slides on the outside of the abutment 203 and squeezes the hollow sleeve 3031 on the inside. The hollow sleeve 3031 squeezes the upper unit buffer pad 3033, and the upper unit buffer pad 3033 squeezes the moving column 3032. At this time, a certain amount of buffering can be achieved. At the same time, the moving column 3032 squeezes the lower unit buffer pad 3034 to achieve secondary buffering. The two work together to reduce the rigid transmission force between the implants 1, making the use of the implants 1 more natural. Both the upper unit buffer pad 3033 and the lower unit buffer pad 3034 are made of PEEK material, which has the advantages of high temperature resistance, high strength, corrosion resistance, biocompatibility and lightweight, and can ensure the long-term use of the product. They are installed on the outside of the limit cover 301, and the limit cover 301 covers the outside of the repair base 2, which can achieve the purpose of stable connection.

[0021] Example 2 This embodiment is a further improvement on embodiment 1. Please refer to [link / reference]. Figure 1 and Figure 2 The implant 1 includes a connector 101 and a central post 102. The connector 101 has external threads on its outer side, and the central post 102 is located in the center of the inner side of the connector 101. The bottom of the central post 102 is fixedly connected to the connector 101, and the outer side of the central post 102 is spirally connected to the repair abutment 2.

[0022] The repair abutment 2 includes a connecting post 201 that is spirally connected to the inside of the connector 101. The bottom of the connecting post 201 is fixedly connected to an internal threaded connecting sleeve 202. The inner side of the internal threaded connecting sleeve 202 is spirally connected to the implant 1. The top of the connecting post 201 is fixedly connected to an abutment 203. A threaded hole 205 that is spirally connected to a central screw 4 is opened in the center of the top of the abutment 203.

[0023] The surface of the base 203 is provided with uniformly distributed limiting holes 204.

[0024] The mating structure formed by the connecting post 201 of the repair abutment 2 and the internal threaded connecting sleeve 202 can be assembled with the connecting body 101 and the central post 102 of the implant 1. The connection structure adopts the connection form of internal and external threads, which can ensure the connection strength and tightness between the implant 1 and the repair abutment 2, prevent the connection from becoming loose, and thus avoid negative impact on the stability and effect of the implant. Also includes the following: The limiting holes 204 cooperate with the buffer sleeves 303 to achieve the positioning purpose. At the same time, the setting of multiple buffer sleeves 303 can share the pressure and ensure that the implant 1 is less uncomfortable during use. The crown is set on the outside of the limiting cover 301. The central screw 4 is connected to the restorative abutment 2. The limiting cover 301 between the central screw 4 and the restorative abutment 2 can move to a certain extent, which facilitates its cooperation with the buffer sleeve 303 to achieve the buffering purpose. The recessed groove 304 is used to hide the nut of the central screw 4 to prevent the crown from contacting it and affecting the subsequent buffering purpose.
